Dark matter-baryons separation at the lowest mass scale: the Bullet Group
F. Gastaldello, M. Limousin, G. Foëx +13
We report on the X-ray observation of a strong lensing selected group, SL2S J08544-0121, with a total mass of which revealed a separatio…
Sloshing cold fronts in galaxy groups and their perturbing disk galaxies: an X-ray, Optical and Radio Case Study
F. Gastaldello, L. Di Gesu, S. Ghizzardi +10
We present a combined X-ray, optical, and radio analysis of the galaxy group IC 1860 using the currently available Chandra and XMM data, literature multi-object spectroscopy data a…
Studying the WHIM Content of the Galaxy Large-Scale Structures along the Line of Sight to H 2356-309
L. Zappacosta, F. Nicastro, R. Maiolino +5
We make use of a 500ks Chandra HRC-S/LETG spectrum of the blazar H2356-309, combined with a lower S/N spectrum of the same target, to search for the presence of warm-hot absorbing…
Low-Mass X-ray Binaries and Globular Clusters in Early-Type Galaxies. I. Chandra Observations
Philip J. Humphrey, David A. Buote
We present a Chandra survey of LMXBs in 24 early-type galaxies. Correcting for detection incompleteness, the X-ray luminosity function (XLF) of each galaxy is consistent with a pow…
Large scatter in X-ray emission among elliptical galaxies: correlations with mass of host halo
W. G. Mathews, F. Brighenti, A. Faltenbacher +4
The enormous range of X-ray luminosities among elliptical galaxies with similar optical luminosities can be attributed to large scatter and systematic variations in the dark halo m…
The X-Ray Concentration-Virial Mass Relation
David A. Buote, Fabio Gastaldello, Philip J. Humphrey +4
We present the concentration (c)-virial mass (M) relation of 39 galaxy systems ranging in mass from individual early-type galaxies up to the most massive galaxy clusters, (0.06-20)…
